Definitions
- This application is related to wireless communications.
- Figure 1 shows an overview of an Evolved Universal Mobile
- E- UTRAN 100 Telecommunications System (UMTS) Terrestrial Radio Access Network (E- UTRAN) 100 in accordance with the prior art.
- E- UTRAN 100 includes three eNodeBs (eNBs) 102, however, any number of eNBs may be included in E-UTRAN 100.
- the eNBs 102 are interconnected by an X2 interface 108.
- the eNBs 102 are also connected by an Sl interface 106 to the Evolved Packet Core (EPC) 104.
- the EPC 104 includes a Mobility Management Entity (MME) 108 and a Serving Gateway (S-GW) 112.
- MME Mobility Management Entity
- S-GW Serving Gateway
- a WTRU transmits a SERVICE REQUEST message to an eNB.
- the WTRU starts a timer, such as timer T3417ext, for example.
- the WTRU enters EMM-SERVICE- REQUEST-INITIATED state.
- the WTRU determines that a user plane radio bearer is set up and therefore the procedure is successful.
- the WTRU stops the timer and enters an EMM-REGISTERED state.
- Figure 3 is a signal diagram of a service request procedure 300 in accordance with the prior art.
- An eNB 302 transmits a circuit switched (CS) call request 304 to a WTRU 306.
- CS circuit switched
- the eNB 302 also transmits a CS service notification 308 to the WTRU 306.
- the WTRU 306 responds to the eNB 302 with an extended service request (ESR) message 310.
- ESR extended service request
- the WTRU 306 then starts a timer 312. If the NAS security mode control procedure is completed 314, or if NAS radio bearers are established 316 or a service reject message 318 is received by the WTRU 306, the timer is stopped 320. [0009] If the WTRU 306 is in an EMM-CONNECTED mode when the
- ESR 310 is transmitted to the network, NAS security 314 may already be established. Furthermore, if the WTRU receives a change cell message or a handover command, no bearers are setup. Consequently, other than receiving a service reject message, which indicates a failure of the service request procedure, the WTRU will not stop the timer even though the service request procedure was successful.
- the network may not initiate the security mode procedure.
- the security mode procedure is a network operator option and may not be implemented by all operators. In this instance, the WTRU 306 may not use the completion of the security mode procedure as an indication to stop the timer, and the timer may continue to run.
- a method and an apparatus are disclosed for operating a timer in a WTRU.
- the WTRU may be in a connected mode.
- the receiver of a WTRU may be configured to receive a circuit switch (CS) call request.
- the transmitter of the WTRU may be configured to transmit an extended service request (ESR) in response to the CS call request.
- ESR extended service request
- the WTRU may be configured to start a timer in response to the transmittal of the ESR.
- the receiver of the WTRU may be configured to receive a handover command in response to the transmittal of the ESR, and the WTRU may be configured to stop the timer upon reception of the handover command.

- the WTRUs 410 may operate in one of two mobility states. When at least one of the WTRUs 410 has no non-access stratum (NAS) signaling connection between the WTRUs 410 and the eNB 420, it may be in an EMM-IDLE mode. When one of the WTRUs 410 establishes an NAS signaling connection, it is in an EMM- CONNECTED mode.
- NAS non-access stratum
- Each of the WTRUs 410 may use a service request procedure to transfer their EMM mode from EMM-IDLE to EMM-CONNECTED and to establish radio bearers to send uplink (UL) user data.
- UL data is data that is sent from the WTRUs 410 to the eNB 420.
- the service request procedure may also be used to invoke a mobile originating (MO) or mobile terminating (MT) circuit switched (CS) fallback procedure.
- the procedure may also be used when the network has downlink (DL) signaling pending, one of the WTRUs 410 has UL signaling pending, one of the WTRUs 410or the eNB 420 has user data pending and the WTRU for which the user data is intended is in EMM-IDLE mode, or when one of the WTRUs 410 is in EMM-IDLE or EMM-CONNECTED mode and has requested to perform MO or MT CS fallback.
- DL downlink
- the service request procedure may be initiated by at least one of the WTRUs 410.
- a trigger may be sent by the eNB 420 in a paging message.
- the WTRU targeted by the paging message may invoke the service request procedure when the WTRU receives the paging message, has pending user data to be sent, or has pending UL signaling.
- a WTRU in EMM- IDLE or EMM-CONNECTED mode may invoke the service request procedure when the WTRU receives a CS fallback request or receives a notification for a CS call, such as a page or a service notification.

- An eNB 602 transmits a CS call request 606 and a CS service notification 608 to a WTRU 604.
- the WTRU 604 which is in connected mode, transmits an extended service request 610 to the eNB 602.
- the WTRU starts a timer 612.
- the WTRU 604 receives a handover command 614 and the WTRU stops the timer 616. Therefore, along with the other criteria for stopping the timer, as shown in Figure 6, the WTRU 604 stops the timer 616 when it receives a handover 614 or cell change command. If the timer expires prior to a mobility message being received by the WTRU 604, such as a handover command or cell change command, the procedure is aborted.
- FIG. 7A is a signal diagram showing a method to stop a timer 700 when an ESR message is sent with an indication of call rejection in accordance with an embodiment.
- An eNB 702 sends a CS call request 706 and a CS service notification 708 to a WTRU 704.
- the WTRU 704 sends an EMM service request message including a CS call rejection indication 710 to the eNB 702.
- the timer is started 712 once the extended service request message with the CS call rejection indication 710 is transmitted.
- the timer is the stopped 714.
- the timer may be stopped 714 immediately after the extended service request message 710 is transmitted. Alternatively, the timer may be stopped after a predetermined time has elapsed, for example, after half the time that the timer would have run if the CS call was accepted.
- the NAS entity may receive a notification from a lower layer entity, such as the RRC or MAC, for example, that acknowledges the transmittal of the ESR.

- the receipt or transmission of the message triggers the WTRU to stop the timer 714.
- the timer may be allowed to expire without the
- the WTRU 702 determining that the expiration of the timer indicates a problem. Furthermore, the timer may not be started at all if the CS call is rejected. The stopping of the timer indicates the fallback procedure was completed successfully.
